VISE

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed May 27,1907- Serial No. 375,862.

To all whom 'it may concern:

Be it known that I, DANIEL R. CHAsn, a citizen of the United States,residing at Finley, in the county of Steele and State of North Dakota,have invented certain new and useful Improvements in Vises; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to vises or work-holders used by jewelers andothers for holding small articles while being soldered; and it consistsin the novel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure l is a front view ofthe vise. Fig. 2 is a planview of the vise. Fig. 3 is an end view of the same. Fig. 4 is a sideview of an alternative form of vise-jaw used for collar buttons. Fig. 5is a plan view of the jaw shown in Fig. 4. I

A is a supporting base, provided with brackets or blocks a. B is acylindrical shaft which is secured in the said brackets.

O is a work-table which is connected to a tubular pillar in by a balland socket joint 12 of any approved construction. This ball and socketjoint enables the table to be turned around and to be set at any desiredangle. The tubular pillar b is slidable over a spindle C which projectsfrom a socket c. The socket c is slidable longitudinally and adjustablecircumferentially upon the shaft B, and e is a clamping screw forsecuring the socket in position. The said pillar and spindle form atelescopic support for the table, and O is a set-screw for holding thetubular pillar in any desired position upon the said spindle. D are twosimilar vises supported by the said shaft B, one upon each side of thesaid table. with this exception, they are both alike, the descriptionwill be confined to one of theml Each vise is provided with a socket Ewhich is adjustable longitudinally and circumferentially on the shaft B,and which is provided with a set-screw e for holding it in position. Thesocket E is provided with a quadrant-plate F having a curved slot f. i 1

G is a spindle provided with a forked jaw g at its lower end which ispivoted to the said quadrant-plate by a pin 9. H is a clamping bolt orscrew which engages with the said jaw, and which is slidable in the saidcurved slot. This bolt H enables the spindle to be clamped to the socketafter it has been adjusted to any desired angle.

1 is the tubular shank of a vise jaw which is slidable upon the spindleG, and i is a set-screw for securing the said shank to the said spindleafter the position of the vise jaw has been adjusted. The vise D isprovided with any approved form of vise jaws, The two jaws forming eachpair of jaws are pivotally connected to- One vise is longer than theother, but, as,

gether by pins 70 and a link It. These pivoted vise jaws are preferablyprovided with an opening spring j, and a slidable locking-collar or ringj, but they may be of any other approved construction in carrying outthis invention.

In the form of jaw shown in Figs. 4 and 5, a tubular shank I is providedwhich is adjustable upon one of the spindles G, in a similar manner tothe shank I. The shank I is provided with a rectangular end portion 2,and 3 is a forked jaw which engages loosely with this end portion 2 sothat the jaw 3 is free to move pivotally in a vertical direction. A pin4 is provided for retain-' ing the jaw in engagement with the said endportion. A spring 5 is provided and secured between the said forked jawand the shank I, so that the forked outer end portion 6 of the jaw ispulled downwardly, and is thereby adapted to hold a collar button orother small article upon the table.

The vise jaws and the table are slid and adjusted so as to hold the workto the best advantage, and the soldering is effected while the work isheld in the best possible position.

What I claim is:

1. The combination, with a stationary support, of a socket connected tothe said support and provided with a quadrant-plate, a telescopicsupport pivoted to the said quadrant-plate and provided with alocking-device, means for engaging the work carried by the saidtelescopic support, and a table for supporting the work also carried bythe said stationary support.

2. The combination, with a stationary support, of a socket connected tothe said support and provided with a quadrant-plate, a telescopicsupport pivoted to the said quadrant plate and 'provided with alocking-device, a jaw for holding the work loosely connected to the saidtele scopic support, a spring which moves the said jaw downwards, and atable for supporting the work under the said jaw also carried by thesaid stationary support.

3. The combination, with a stationary support, of a socket connected tothe said support and provided with a quadrant-plate, a telescopicsupport pivoted to the said quadrant-plate and provided with a lockingdevice, means for engaging the work carried by the said telescopicsupport, a second telescopic support also carried by the said stationarysupport, and a table for supportingthe work provided with a universalball and socket joint which connects it to the last said telescopicsupport.

4. The combination, with a base, and a shaft secured thereto; of twoadjustable vises adjustably connected to the said shaft, each said visecomprising a socket for en gaging the said shaft provided with aquadrant-plate, a spindle provided with a forked end portion which ispivoted to the said plate, a fastening device for securing the saidspindle to the said plate, and means for engaging the work provided witha tubular shank which is adjustable on the said spindle.

In testimony whereof I have affixed my signature in the presence of twowitnesses.

DANIEL R. CHASE.
